I don't use a headset. My car has both an aux-in, and a USB port in the console. If I connect an MP3 player to the USB it charges, plays through the car stereo. I could do the same with the Droid but then my phone would be in the console, so I was hoping to use BT for the music. The Moto D200 is supposed to be able to stream music from a PC to a BT headset, and it is listed as being compatible with the Droid so how would it be used other than what I'm thinking?
